Samsung didn't implement convergence, they implemented Android-with-a-keyboard-on-a-big-screen . True convergence would be something like Ubuntu Touch wanted to do
I think it's really interesting what Apple are trying to do (with Marzipan, pro apps for iPad, desktop level SoC's) but I think they still have a couple of years work ahead of them. It's not an easy task, especially with so much legacy.
Getting Adobe and Autodesk to rewrite their flagship software for iOS was quite a good win, though I still wonder how those compare to the desktop versions
Now if they could only get Apple to rewrite their flagship Pro software for iOS.
